Application fil d June 1, 1896. Serial No. 593,922. (No model.)

To all whom zit may concern.-

Be it known that I, ROBERT MUNN DIXON, of East Orange, county of Essex,State of New Jersey, have invented certain new and useful Improvementsin Oar-Heaters, of which the following is a specification, referencebeing had to the accompanying drawings.

The object of my invention is to produce an improved directsteam-heating system in which the radiating-pipes are carried preferablyon both sides of the car and in which such provision is made forconnecting or disconnecting them to the main train-pipe as will permitready connection and disconnection without disturbance of theradiatingpipes.

In canheatiug systems the radiators or radiating-pipe sections areconnected with a train-pipe through connections that pass through awall, usually the floor, of the car.

In car-heating systems ordinarily the radiating-pipes through theirexpansion and contraction tend to distort and disturb the relativepositions of the connections which exist between them and the main trainpipe or pipes.

My invention is designed to provide upon a car a rigidly-fixed fitting,to which connection with the train-pipe can be made on one side and withwhich upon the other the radiating-pipes are connected. By thisarrangement, the end'of the radiating-pipes not connected with thefitting being movable, all movement from expansion and contraction 3 5of the radiating-pipes is made in one direction without disturbing theconnection with the train-pipe or the intermediate fitting, throughwhich union with those connections and the radiatingpipes is effected.

40 In the accompanying drawings, Figure I is a top plan View of myheater complete. Fig. 11 is a side elevation of one side thereof. Fig.III is an end view, on an enlarged scale, looking toward the valve. Fig.IV is a side elevation, partly in section, of the valve and connectionsfor uniting it to the radiatingpipes. Fig. V is a sectional view lookingtoward the drainage end of the system. Fig. VI shows a modified form ofdrainage-piping adapted for use in cars not having cross-seats.

Referring to the figures on the drawings, 1 indicates the main trainpipeon a car, provided with the usual means (not illustrated) for makingconnection with the train-pipes upon a contiguous car. It is providedwith suitable valves 2 and 3, as usual, and connects with branch pipesat and 5, as through a four-way fitting 6. The branch pipes at and 5,through elbows 7 or other connections for the purpose, are carriedupthrough the floor 8 of a car, (see Fig. 11,) where they enter on oneside a valve-case 9. It is therefore sufficient to describe theconnection of one of the pipes, as 5, with the valve and radiatingsystem on one side of the car. 6

Referring particularly,therefore,to Fig. II, it is deemed sufficientlydescriptive of the valve for the purpose of this specification to saythat it is designed that the operation of its plug,controlled by thelever 10,shall estab- 7o lish communication between the pipe 5 andeither or both of the valve branches l1 and 12. These valve branchescommunicate, respectively, with radiating-pipes 13 and 14:.

To carry out my idea of rendering the radiating-pipes comparativelypermanent within the car and fixed at one end therein independently ofthe valve and trainpipe connections, I provide on the end of eachradiating-pipe next to the valve an intermediate 8o fitting 15, which,screwing upon the end of the radiating-pipe, receives a smaller pipe 16,which screws into it at one end and which is designed to be fastened atthe other end to its appropriate valve branch. Each of the fittings 15is provided with suitable means-as, for example, aflange 17-by which itmay be firmly secured to the side frame of the car, as by bolts 18. Iprefer to provide the valve branches with ground-joints 19, into which 0the ground ends 20 of the pipe 16 fit, the parts 19 and 20 being securedtogether by an annular union 21. Through the operation of the unions 21the valve maybe readily united to or disconnected from theradiating-pipes without disturbing the latter. One end of each of theradiating-pipes being securely fixed to the side frame of the car by itsfitting 15, it is fixed there independently of the train-pipeconnections and the valve mechanism. Its zoo position is permanent, andadjustments can always be made with reference to such fixed position.Moreover, all considerable and ma terial expansion occurs in theradiating-pipes. The radiating-pipes are made free to ex pand in thedirection of their ends opposite the fittings 15, but being fixed at oneend by those fittings cannot through their expansion and contractiondisturb their adjustments with respect to the valve or those of thevalve with respect to its pipe connections. The ends of the pipes 13 and14 opposite the fittings 15 may be loosely supported by any suitablemeans, not necessary to illustrate.

22 indicates the drain-pipes, 23 the draintip, and 24 a cock between thedrain-pipe and drain-tip, which is provided, as usual, with a minuteopening for ordinary drainage, but which is adapted upon being fullyopen to secured to the fitting being loosely secured to the car,substantially as and for the purpose specified.

In testimony of all which I have hereunto subscribed my name.

ROBERT MUNN DIXON.
